Iridium Catalysts & Compound

The iridium catalyst proved to be more stable under a wide range of conditions,and more soluble so that it has no tendency to precipitate out of solution. This means that the catalyst can be continuously recycled within the plant. New catalyst does not need to be added. As well as this iridium is considerably cheaper
